Secrets provide a mechanism for securely adding sensitive data, such as passwords, tokens, or keys, to the containers of a Preview deployment. Secrets are similar to environment variables, but they are intended for confidential data. Secrets are defined as name/value pairs and are injected at runtime.
Secrets can be added in the Uffizzi Dashboard (Project > Project Settings > Secrets). Once added, they cannot be viewed or edited. To update a secret, you should delete the old secret and create a new one. Secrets added in the Project Settings must be invoked in your Uffizzi Compose file, as described here.
